论文摘要
我们建议使用$ su（1,1）$对称的系统的$ {s} $ - 使用$ {q} $和$ {p} $符号之间的连接来计算具有$ su（1,1）$对称系统的$ {s} $的实用配方。分析了在两层倍曲面的上纸上定义的自偶（Wigner）相位空间函数的特殊情况（或等效地，在庞加莱盘内）。
We propose a practical recipe to compute the ${s}$-parametrized maps for systems with $SU(1,1)$ symmetry using a connection between the ${Q}$ and ${P} $ symbols through the action of an operator invariant under the group. The particular case of the self-dual (Wigner) phase-space functions, defined on the upper sheet of the two-sheet hyperboloid (or, equivalently, inside the Poincaré disc) are analyzed.
